Hitoshi Shinso is an experimental psychologist from the New Musutafu Laboratory/NML. He's been dabbling in more inhumane experiments on his subjects, mostly human, by using his quirk and some 'tools' to really see the mental effects of torture- all in secret, of course. He wouldn't want to lose his job now, would he? He's incredibly careful not to let anything slip around his coworkers, but his new intern is looking perfect for an experiment he has in mind.
